Description

Technical Field

[0001] This utility model relates to the field of vacuum furnace technology, specifically to a high-temperature molybdenum belt heating vacuum furnace. Background Technology

[0002] Molybdenum metal is a rare and refractory metal. Molybdenum heating belts are widely used in the manufacturing of high-temperature vacuum furnaces due to their good high-temperature physical stability, lack of pollution, and ability to be used for extended periods at 1700℃. Existing high-temperature molybdenum belt heating vacuum furnaces typically use manual operation for loading and unloading. This method not only increases labor intensity and reduces efficiency but also poses a risk of burns to operators from the high-temperature furnace walls. While some automated loading and unloading structures are located inside the furnace body, the long-term high temperatures inside place extremely high demands on their structural materials, resulting in a short service life. Furthermore, the molybdenum belt inside the furnace is prone to brittleness or deformation under prolonged high temperatures, affecting the overall lifespan of the vacuum furnace. Therefore, this paper proposes a high-temperature molybdenum belt heating vacuum furnace.

[0003] To address the aforementioned technical issues, Chinese Patent No. CN216954075U discloses a high-temperature molybdenum strip heating vacuum furnace, comprising a furnace body with multiple sets of heating strip assemblies inside the furnace body. All sets of heating strip assemblies are electrically connected to external heating electrodes. Loading and unloading mechanisms are provided on the left and right sides of the furnace body. The loading and unloading mechanisms include two connecting seats, which are respectively fixed on the left and right sides of the furnace body. Each of the two connecting seats is equipped with an electric telescopic rod.

[0004] While the aforementioned existing technical solutions avoid burns to operators and improve the efficiency of loading and unloading, and the external structure is not subjected to high temperatures inside the furnace for extended periods, the connecting seat is fixedly connected to the outer wall of the furnace body, the electric telescopic rod is installed inside the connecting seat, and the connecting plate is also fixedly connected to the output end of the electric telescopic rod. This makes it difficult for workers to quickly separate the clamping components and the electric telescopic rod to repair or replace faulty parts, thereby affecting the maintenance efficiency of the workers.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A high-temperature molybdenum strip heating vacuum furnace includes a furnace body 1. Both sides of the outer wall of the furnace body 1 are equipped with docking seats 2. An electric telescopic rod 5 is attached to one side of each docking seat 2. Clamping assemblies are installed at the output ends of the two sets of electric telescopic rods 5. The electric telescopic rods 5 are engaged with the docking seats 2 via a locking mechanism. The locking mechanism includes an overlapping plate 3, a rubber pad 4, a reset locking assembly, and a dragging assembly. The overlapping plate 3 is installed on one side of the outer wall of the electric telescopic rod 5, and the rubber pad 4 is installed on one side of the docking seat 2. The reset locking assembly locks the positions of the electric telescopic rods 5 and the clamping assembly, while the dragging assembly unlocks them. This device features a simple structure, convenient operation, and allows workers to quickly assemble and disassemble the electric telescopic rods 5 and the clamping assembly for timely maintenance, ensuring efficient subsequent work.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the reset locking assembly includes a docking block 6 installed on one end of the outer wall of the overlapping plate 3. Both ends of the rubber pad 4 are provided with through holes. The docking block 6 is slidably connected to the through holes. A docking groove is provided on one side of the docking seat 2 corresponding to the through holes. The docking groove is slidably connected to the docking block 6. A locking groove is provided on one side of the docking groove inside the docking seat 2. A limit seat 7 is installed on one side of the inner wall of the locking groove. A pressure plate 8 is overlapped on the top of the limit seat 7. First, the clamping assembly is placed inside the furnace body 1. Then, the overlapping plate 3 is overlapped on the outer wall of the rubber pad 4, so that the docking block 6 slides into the inner side of the docking groove through the through hole. Continue to press down to make the rubber pad 4 retract. The docking block 6 gradually moves down and abuts against the inclined surface on the pressure plate 8, forcing the pressure plate 8 to drive the limit block 9 to slide inside the limit groove. At the same time, the first spring 10 is squeezed and the second spring 17 is stretched. As the docking block 6 continues to descend, it contacts the abutment plate 11 and forces the rotating rod to rotate.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a limiting groove is provided at the top of the limiting seat 7, and a limiting block 9 is slidably connected to the inner side of the limiting groove. One end of the limiting block 9 is fixedly connected to one side of the pressing plate 8. A first spring 10 is installed between one side of the limiting block 9 and the inner wall of the limiting groove. A tension groove is provided on one side of the pressing plate 8, and a second spring 17 is installed between the inner wall of the tension groove and the inner wall of the locking groove. Then, the torsion spring 12 retracts until the abutment groove is close to the rotating groove. The abutment plate 11 is popped out to the inner side of the abutment groove by the torsion spring 12. Then, the overlapping plate 3 is no longer squeezed, so that the rubber pad 4 rebounds a small distance, and the connecting block 6 also moves a small distance, so that one end of the abutment plate 11 can abut against the inner wall of the abutment groove, thus completing the installation of the electric telescopic rod 5 and the clamping assembly.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, both the mating block 6 and the pressing plate 8 have mutually fitting inclined surfaces at their opposite ends. The pressing plate 8 has a rotating groove on its inclined surface inside, with a rotating rod rotatably connected to the inside of the groove. An abutment plate 11 is fitted onto the outside of the rotating rod, and one side of the abutment plate 11 has a slope that fits against the inclined surface. A torsion spring 12 is installed between the rotating rod and the inner wall of the rotating groove. The mating block 6 has an abutment groove on its inclined surface inside. The dragging assembly includes an installation groove on one side of the mating block 6, with a movable rod 13 installed inside the installation groove. The mating seat 2 has an operating groove on one side of the locking groove inside, with a pull ring 14 rotatably connected to one end of the movable rod 13 extending into the operating groove. The mating seat 2 has an operating groove and a locking groove inside the operating groove. A movable groove is provided between the movable rod 13 and the movable groove. Further, when it is necessary to disengage the positioning to inspect and maintain the electric telescopic rod 5 and the clamping assembly, the pull ring 14 is then fastened to drive the movable rod 13 to slide inside the movable groove, while the pressure plate 8 moves synchronously. The first spring 10 is squeezed again and the second spring 17 is stretched, so that the abutment plate 11 moves horizontally away from the inside of the abutment groove. At this time, the abutment block 6 is no longer abutted, and the rubber pad 4 rebounds completely. The abutment block 6 will move a distance inside the abutment groove as the rubber pad 4 bounces up. At this time, the pull ring 14 will not be locked again. Then the electric telescopic rod 5 and the clamping assembly can be removed together for inspection and maintenance.

[0028] In this embodiment, as Figure 1 and Figure 4As shown, the clamping assembly includes a connecting plate installed at the output end of the electric telescopic rod 5. A positioning frame 15 is installed at the opposite ends of the two sets of connecting plates. An adjusting cylinder 16 is installed at one end of the inner side of the positioning frame 15. An adjusting groove is opened on one side of the adjusting cylinder 16. A threaded rod 21 is rotatably connected to the inner side of the adjusting groove. The threads at both ends of the outer wall of the threaded rod 21 are opposite. Adjusting plates 18 are threadedly connected to both ends of the outer side of the threaded rod 21. The adjusting plates 18 and the adjusting groove are slidably connected. A first motor 19 is installed on one side of the outer wall of the positioning frame 15. The driving end of the first motor 19 extends to the inner side of the adjusting groove and is fixedly connected to one end of the threaded rod 21. A clamping plate 20 is installed on one side of the adjusting plate 18. Furthermore, after the electric telescopic rod 5 and the clamping plate 20 are positioned, the first motor 19 can be started to drive the threaded rod 21 to rotate, so that the clamping plate 20 clamps the material. Then, the electric telescopic rod 5 is started to drive the clamping plate 20 to move, so as to perform material loading and unloading operations.

[0029] The implementation principle of a high-temperature molybdenum strip heating vacuum furnace according to an embodiment of this application is as follows: The clamping assembly is placed inside the furnace body 1. Then, the overlapping plate 3 is overlapped with the outer wall of the rubber pad 4, allowing the mating block 6 to slide into the mating groove through the through hole. Continuing to press downwards causes the rubber pad 4 to retract, and the mating block 6 gradually moves downwards to abut against the inclined surface on the pressing plate 8. This forces the pressing plate 8 to drive the limiting block 9 to slide within the limiting groove, simultaneously compressing the first spring 10 and stretching the second spring 17. As the mating block 6 continues to descend, it contacts the abutting plate 11, forcing the rotating rod to rotate, and the torsion spring 12 to retract. Until the abutting groove approaches the rotating groove, the abutting plate 11 is ejected by the torsion spring 12 to the inside of the abutting groove. Then, the overlapping plate 3 is no longer compressed, causing the rubber pad 4 to rebound a short distance, and the mating block 6 also moves a short distance, allowing one end of the abutting plate 11 to abut against the inner wall of the abutting groove, thus completing the connection between the electric telescopic rod 5 and the clamping assembly. When installing, if it is necessary to disengage the positioning to inspect and maintain the electric telescopic rod 5 and the clamping assembly, then fasten the pull ring 14 to drive the movable rod 13 to slide inside the movable groove, and at the same time drive the pressing plate 8 to move synchronously, squeeze the first spring 10 again and stretch the second spring 17, so that the abutting plate 11 moves horizontally away from the inside of the abutting groove. At this time, the abutting block 6 is no longer abutted, and the rubber pad 4 rebounds completely. The abutting block 6 will move a distance inside the abutting groove as the rubber pad 4 bounces up. At this time, releasing the pull ring 14 will not cause a jamming situation again. Then the electric telescopic rod 5 and the clamping assembly can be removed together for inspection and maintenance. After the position of the electric telescopic rod 5 and the clamping plate 20 is completed, the first motor 19 can be started to drive the threaded rod 21 to rotate, so that the clamping plate 20 clamps the material. Then the electric telescopic rod 5 is started to drive the clamping plate 20 to move, so as to perform material loading and unloading operations.

[0030] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
